We don't need to pass x(0), x(1), and x(2) because they
can already be found in the register array.

Keep frequently used variables in machine registers.

We expect that:
* An arithmetic instruction is more likely to succeed
than to fail.
* An arithmetic instruction is more likely to have small
operands than bignum operands.
|
|
In a correct Erlang programs, we can expect that:
* A GC test instruction (such as test_heap) is more likely
not to do the GC.
* A BIF is more likely to succeed than to fail.
* A BIF is more likely to fail in a guard than in a body.
* An apply or fun call is likely to succeed.
Annotate conditions accordingly.

Instructions that used to be implemented in beam_emu.c
were not marked as cold as it would make no difference.
|
|
The bit syntax instructions are mixed among other instructions
in beam_hot.h and beam_cold.h.
Introduce a new hotness level called '%warm' with is associated
file beam_warm.h. Mark all bit syntax instructions as '%warm'.

Remove backward compatibility support for float literals
OTP-14575

beam_validator could fail issue a diagnostic when a register
that was supposed to be a match context was not guaranteed to
be a match context.
The bug was in merging of types. Merging of a match context with
another term would result in a match context. That is wrong. Merging
should produce a more general type, not a narrower type. Also, the
valid slots in two match contexts should be combined with 'band', not
'bor'.

We start the port in the started process in order
to get the messages in the correct place and also
so that unloading the port driver does not kill the
test process.

Remove query keyword residues
|
|
Otherwise processes doing io could get stuck.
See ERL-472.
|
|
Decoded CER/CEA messages are passed in events messages that can be
subscribed to using diameter:subscribe/1. A configured decode_format was
not reflected in these, messages always being passed as records.
Clarify that strict_arities only applies to message callbacks.

Starting from R16B, floating point constants are stored
in the literal pool.
The backward compatibility support for the old representation
of floats has been kept long enough. Also, we might want to
ensure that all literals are unique in the future, and we certainly
don't want to update this code to ensure uniqueness.

Remove time-consuming ethread_SUITE from smoke tests

The ethread_SUITE is unlikely to ever find a real bug
introduced in a pull request, but it frequently times
out when run by Travis CI.

When cleaning selects, it might happen we're left with only one pair. In such
case convert to a regular test + jump.

query was no longer a keyword since the commit 0dc3a29744bed0b7f483ad72e19773dc0982ea50 2012-11-19.
So the quotes around query, when it used as atom, no needed.

Since these can make sense per peer. The remaining service-only options
either belong there or make little sense being configured per transport.
|
|
Only a default spawn_opt has been possible to configure, but there's
no reason why most others should need to be configured per transport.
Those options that still only make sense on a transport are
transport_module/config (because of the semantics of multiple values),
applications/capabilities (since these override service options), and
private (since it's only to allow user-specific options in a backwards
compatible way).
